GRN's new Saber is a "solid-state" digital audio player. The playback system is entirely electronic, with no moving parts. It uses the commonly available MP3 or WMA formats to enable large amounts of audio to be stored and played back at high quality. The audio files can be easily loaded by the user from a computer via the in-built USB port.

The player incorporates a speaker and high-efficiency digital amplifier, making it ideal for group listening. A heavy-duty hand-crank mechanism is coupled with a rechargeable battery to ensure that power is always available. The battery can also be recharged from an external source, such as a solar panel, via the DC socket.

The player has been designed with the goals of high reliability and long life under adverse conditions. The case is made of tough ABS plastic, with impact-absorbing Neoprene corners. The keypad uses high reliability switches beneath a tough membrane. The player is highly dust-resistant.
